推荐答案

根据这，你做的正确。也许尝试设置一个等于 {Command.path} 的公式字段，然后使用它来看看水晶是否没有正确解析？这样，您可以显示公式字段并查看其显示方式。也许你用DB引号或空格来存储它？或者，使用参数应该肯定有效，因此您可以使用 {Command.path} 作为用于加载映像的参数来创建子报表。

According to this, you're doing it right. Perhaps try to set a formula field equal to {Command.path} and use that instead to see if crystal just isn't parsing it properly? That way you can display the formula field and see how it displays. Perhaps you're storing it in the DB with quotation marks or spaces? Alternatively, using a parameter should definitely work, so you could make a sub-report with {Command.path} as a parameter that it uses to load up the image.
